#     
#     Pull io_uring updates from Jens Axboe:
#      "This contains:
#     
#        - Support for recvmsg/sendmsg as first class opcodes.
#     
#          I don't envision going much further down this path, as there are
#          plans in progress to support potentially any system call in an
#          async fashion through io_uring. But I think it does make sense to
#          have certain core ops available directly, especially those that can
#          support a "try this non-blocking" flag/mode. (me)
#     
#        - Handle generic short reads automatically.
#     
#          This can happen fairly easily if parts of the buffered read is
#          cached. Since the application needs to issue another request for
#          the remainder, just do this internally and save kernel/user
#          roundtrip while providing a nicer more robust API. (me)
#     
#        - Support for linked SQEs.
#     
#          This allows SQEs to depend on each other, enabling an application
#          to eg queue a read-from-this-file,write-to-that-file pair. (me)
#     
#        - Fix race in stopping SQ thread (Jackie)"
